2 Claims. (01. 210-515) This invention relates to improvements in cartons and more especially to the type designed for the delivery and storage of milk.

It is one of the principal objects of the invention to provide a carton of this character which is of simple, inexpensive and sanitary construction and within which is formed a cream chamber provided with means for opening the chamber to receive the cream as it rises to the top of the milk and for sealing off the chamber When the cream is to be dispensed and the milk is to be retained in the carton.

A still further object is the provision of a new and novel pouring spout formed at one of the uppermost corners of the carton for convenience in dispensing the cream and the milk.

The foregoing and other objects will appear as my invention is more fully hereinafter described in the following specification, illustrated in the accompanying drawing and finally pointed out in the appended claims.

In the drawing:

Figure 1 is a perspective view of a milk carton made in accordance with my invention.

Figure'2 is a bottom plan yiew of Figure 3 showing the cream chamber in aclosed position.

Figure 3 is a sectional elevation taken approximately along the line 33 of Figure 1.

Figure l is a view similar to Figure 2 showing the cream chamber in an open position.

Figure 5 is a fragmentary elevation of the bottomend of the carton showing the folded over construction of the bottom end walls thereof.

Figure 6 is an enlarged fragmentary detail view of a pouring spout associated with the cream chamber and in an open position.

Figure 7 is an enlarged fragmentary sectional view showing the bottom and side wall construction and means for interconnecting the same.

Referring now more particularly to the drawmg:

In Figure 1 reference numeral 1 indicates a carton made in accordance with my invention and having top and bottom walls, 2 and 3 respectively, and four side walls 4 all of the same length and preferably of the same width. In the upper ends of two of the opposing wallsI form an indentation or cavity 5 for convenience in gripping and carrying the carton.

For attaching the bottom wall 3 to the vertical side walls 4, I fold the marginal edges of the bottom wall downwardly as at 6, then upwardly and over on itself, as at l, and again downwardly over on itself, as at 8, to embrace the upwardly folded portion 9 of the side walls 4. These folded and overlapping portions of the bottom and sidewalls are secured together by any approved form of staple ID to provide a leak-proof connectiom Disposed within the carton at its uppermost end is a cream chamber generally indicated at l I and consisting of a top wall I2, side walls l3 and a bottom wall l4 formed with openings l6 (see Fig. 2). A disc I! formed with openings I8 is rotatably mounted in wiping contact with the bottom wall M of the cream chamber by means of a shaft l9 formed with or terminating in, at its lowermost end, a flange 20. The shaft is rotatably mounted within a bushing or bearing 2|, whose lowermost end bears against the bottom wall I 4 of the cream chamber and whose upper end is flanged at 2| to bear against the underside of the top wall l2 of the cream chamber. The upper end of the shaft extends through said upper wall of the cream chamber and is longitudinally bored to receive a squared end 22 of an actuating knob .23 by means of which the disc I! may be rotated from an open to a closed position with respect to the bottom wall of the cream chamber.

When the carton is filled with milk at the dairy, the disc I1 is rotated so that the openings l8 therein are brought into registry with the openings IS in the bottom wall M of the cream chamber to allow the cream to rise up into the cream chamber. When the consumer or user of the carton wishes to dispense the cream only, the disc I! is rotated until the openings I6 and [8 are moved entirely out of registry with each other to seal off the bottom of the cream chamber and to trap the milk within the carton. Then the pouring spout 24, formed as shown and movable about its hinge line, is swung open for convenience in pouring the cream from the chamber. This pouring spout is also used in dispensing the milk after the cream chamber has been opened by again r0- tating the disc I! to allow the milk to pass through it as desired.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes herein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

1. A milk container consisting of a carton having top, bottom and side walls, a cream chamber having top and side walls and an apertured bottom wall, said cream chamber being disposed within said milk container, an apertured disc in rotatable wiping contact with the underside of the bottom wall of said cream chamber, a tubular element having a flange at its upper end and bearing against the underside of the top wall of said cream container and its opposite end bearing against the top side of the bottom wall of the cream container, a core rotatably mounted within said tubular element and having its lower end flanged and secured to said apertured rotatable disc, the opposite end of the core being bored to receive a squared projection of an actuating knob disposed above the top wall of the milk container.

2. A milk container consisting of a carton of box-like formation having top, bottom and side walls. a cream chamber attached to the interior of the carton at its upper end and having top, bottom and side walls, a bearing attached to the 'to be opened and closed by the rotation of said disc, the opposite end of said shaft being provided with a knob for rotating said shaft and said disc, an opening formed in one corner of the container and in a corresponding corner of the cream chamber, and a spout-forming closure for both of said openings.
